Fight Aging! Newsletter, December 31st 2018
In conclusion, there are many anti-aging strategies in development, some of which have shown considerable promise for slowing down aging or delaying the onset of age-related diseases. From multiple pre-clinical studies, it appears that upregulation of autophagy through autophagy enhancers, elimination of senescent cells using senolytics, transfusion of plasma from young blood, neurogenesis and BDNF enhancement through specific drugs are promising approaches to sustain normal health during aging and also to postpone age-related diseases. However, these approaches will require critical assessment in clinical trials to determ...

In conclusion, we found a gradient of increasing blood pressure with higher levels of BMI. The fact that this gradient is present even in the fully adjusted analyses suggests that BMI may cause a direct effect on blood pressure, independent of other clinical risk factors.

Study shows how exercise generates new neurons, improves cognition in Alzheimer's disease
A study by a Massachusetts General Hospital (MGH) research team finds that neurogenesis -inducing the production of new neurons - in the brain structure in which memories are encoded can improve cognitive function in a mouse model of Alzheimer's disease.Research team identifies way to mimic exercise's beneficial effects through pharmacologic and gene therapy."The lesson learned was that it is not enough just to turn on the birth of new nerve cells, you must simultaneously 'clean up' the neighborhood in which they are being born to make sure the new cells survive and thrive.Exercise can achieve that, but we found ways of mi...

In this study, we found that TNF-α resulted in an impairment of autophagic flux in microglia. Concomitantly, an increase of M1 marker expression and reduction of M2 marker expression were observed in TNF-α challenged microglia. Upregulation of autophagy via serum deprivation or pharmacologic activators (rapamycin and resveratrol) promoted microglia polarization toward M2 phenotype, as evidenced by suppressed M1 and elevated M2 gene expression, while inhibition of autophagy with 3-MA or Atg5 siRNA consistently aggravated the M1 polarization induced by TNF-α.
Moreover, Atg5 knockdown alone was sufficient to trigger...

Designer Babies: A Dystopian Sidetrack of Gene Editing
A Chinese scientist shocked the scientific community a couple of days ago with the announcement of having modified the very blueprint of life. If his claims are true, he tried to bestow two baby girls the ability to resist possible future infections with HIV. The outrage shows that humanity is not prepared to utilize the power of gene editing on embryos yet. We have no idea about the biological consequences, and we haven’t tackled the necessary legal and ethical issues.

When Someone Has to Spend Millions on Small Molecule Screening to Get Things Moving
There are any number of reasons why promising lines of research get stuck. Simple abandonment is a surprisingly common one; people outside the scientific community have little appreciation of the degree to which the floor of the forest is littered with valuable raw materials, just waiting for someone to spend the effort to forge them into useful goods. Many researchers have little interest in implementation, or fail to convince funding sources to continue their initial exploration, or the people involved move on, or the tools are hard to use and no-one else wants to make the effort to replicate the discoveries. It is somet...

Top Digital Health Stories of 2018: From Amazon And Google To Gene-Edited Babies
Instead of mind-boggling inventions, 2018 was the year when national governments, as well as healthcare regulators, started to embrace digital health technologies at scale. The year when Google, Amazon, Apple or Microsoft competed head-to-head for the biggest chunks on the healthcare market, and when the buzzword of the year award went to the blockchain. Here’s our guide to the top digital health stories from last year.

This study is the culmination of a decade of research that has repeatedly demonstrated that this vaccine can effectively and safely target in animal models what we think may cause Alzheimer's disease. I believe we're getting close to testing this therapy in people."
Although earlier research established that antibodies significantly reduce amyloid buildup in the brain, researchers needed to find a safe way to introduce them into the body. A vaccine developed elsewhere showed promise in the early 2000s, but when tested in humans, it caused brain swelling in some patients. The new idea was to start with DNA coding for...

Additional Evidence for Lymph Node Degeneration to be an Important Obstacle for Attempts at Thymus Rejuvenation
The thymus atrophies with age, and since its primary function is to support the maturation of T cells, this means that the supply of new T cells, fresh and ready for action, also declines with age. This contributes greatly to immunosenescence, the progressive age-related failure of the immune system to respond to pathogens and destroy damaged or malfunctioning cells. Numerous research groups are attempting to restore the thymus to youthful size and activity, and thus also restore the supply of T cells, and reverse loss of immune function. A wide variety of approaches are under development, from gene therapies and small mol...

AI Doesn ’ t Ask Why — But Physicians And Drug Developers Want To Know
We describe phenomena using science, which gives us a sense of understanding and structure – yet we often lack actual understanding about what we’re observing, or why our treatments work. We have scientific explanations that may appear solid at first glance, but are flimsy upon closer inspection. More commonly, I imagine, we rely on scientific explanations as heuristics to enable us to get through our days, as a scaffold upon which to organize our information.
I suspect AI is viscerally uncomfortable, and challenging to apply to clinical care or drug discovery (see part 2), because of the psychological importance and c...

Initial Evidence for the Antibiotics Azithromycin and Roxithromycin to be Senolytic
Researchers here report on two new senolytic compounds identified in the existing library of approved drugs, based on screening work in cell cultures. It is worth bearing in mind that drug candidates that demonstrate good results in cell culture quite often fail to show promise when tested in animals, so it is wise to be patient as new senolytics work their way through the research and development pipeline. There will be a lot more of this sort of thing in the years ahead, as ever greater amounts of funding pour into finding new ways to selectively destroy senescent cells. Any senolytic approach that removes a significant ...

Senolytic Therapeutics Uses Nanotube-Carried Toxins to Destroy Senescent Cells
Today, I'll point out an analysis from the SENS Research Foundation that covers the approach to selective destruction of senescent cells taken by one of the newly formed biotech startups in the space, Senolytic Therapeutics. This field is hot because it is now well proven that senescent cells are the enemy. They are one of the root causes of aging, accumulating with age to degrade tissue function via the secretion of inflammatory signal molecules. Senescent cells actively maintain an aged, inflamed state of metabolism, resulting in the development of age-related disease and increased mortality.
Senescent cells do se...

Future Trends Help You Choose The Most Fitting Medical Specialty
“I’m a medical student. Which specialty should I choose and what skills will a future doctor need?” “I’m in radiology. Looking at the recent advancements in medical technology, was it a wise choice or should I train myself in something different, too?” These are the questions I most frequently receive after my keynote speeches. While all should be aware of their own physical and intellectual capabilities, here are a few pieces of advice which skills to concentrate on based on the current and future trends in healthcare.
